Abstract (en)
[origin: WO8703366A1] Support frame-free hopper-type weighing device for regulating the throughflow of material as well as the weighed-out quantity for the extrusion of plastics, which is so arranged as to be unaffected by the drive vibrations of the extruder (1). The casing cover-plate (9) which carries the weighing container (11) with the weighing bar is supported via a distance piece (6) and vibration damper (7) on the lower hopper-shaped casing component (4). Extending between the casing cover-plate (9) and the lower casing component (4) is an elastic hose piece (13) which surrounds the weighing container (11), secured at both ends in a sealed manner, and which is made of anti-static filter fabric and/or transparent foil.
